Paleoecologist Curt Stager handily gives the lay readers information about the geological effects that our fossil fuel consumption will have on our planet for millenia to come. Through analogy he deftly informs readers of the scientific concepts that drive the advantages and disadvantages of computer simulations and the actual geophysical evidence of past warm periods in the Earth's deep past. By putting human and animal faces of the consequences of unchecked carbon dioxide emissions, this book is a call to use "relatively objective science" to cut across divisions of "team loyalty, marketing strategies and short-term self-interest" to come together globally to not only reduce carbon dioxide emissions
